Abstract (en)
[origin: WO9846951A1] An automatically controlled seed dryer (30) of the present invention is adapted to efficiently and precisely dry seed by automatically controlling the temperature, direction, and air flow rate, of air flow through the seed within the bin (32, 34). The invention includes an upper plenum (66) for supplying a source of hot air, a lower plenum (68) for supplying a source of ambient air, and a mixing plenum (70) for mixing various proportions of hot and ambient air from the upper and lower plenums (66, 68). The mixing plenum (70) has upper and lower supply doors (72, 74) formed between the mixing plenum (70) and the bin (32, 34) for supplying the mixed air to the bin either above or below the seed. Upper and lower exhaust doors (52, 54) are formed in the bin above and below the seed such that by controlling the operation of the supply and exhaust doors (62, 64, 52,54), the direction and air flow rate of the mixed air through the seed can be precisely controlled by an electronic controller. A plurality of actuators (58, 60, 82, 96) control the operation of the doors.
